HEEL RANDING AND TRIMMING MACHlNE.

SPEGIFICATION forming part of Letters Patent No. 515,492, dated February27, 1 894.

Application filed July 15, 1893. Serial No. 480,671 (N0 model.)

To all whom it may concern:

Be it known that I, JOHN RISAAOSON, a citizen of the United States,residing at Chicago,1u the county of (look and State of Illinois, haveinvented certain new and useful Improvements in Band and Heel TrimmingMachines, of which the following is a specification.

The object of this invention is to construct a machine in which issupported a revolving rand cutter and a revolving heel trimmer, and asupport for the material to be operated upon made movable to properlypresent it to cutters.

In the accompanying drawings,-Figure 1, is a face elevation of myimprovements. Fig. 2, is an edge elevation thereof. Fig. 3, is an innerface view of the cutter supporting frame. Fig. 4, is an inner face viewof the frame for supporting the material. Fig. 5, shows the means foradjusting the toothed rack. Figs. 6, 7 and 8 show the material in thevarious stages of completion. Fig. 9, is a vertical lengthwise sectionthrough the heel pile and operating mechanism.

The supporting frame for the cutters in this instance consists of theplates 1, and 2 connected by a base plate 3. In suitable bearings inthese upright plates are supported a shaft 4, to which is connected aheel trimming cutter 5, a shaft 6, supporting a saw 7, and a maindriving shaft 8, to the outer end of which is secured a pulley 9, andbetween the plates is secured a pulley 10, a band 11, connecting it witha pulley 12, supported by the shaft 6, which also supports a largerpulley 13, having a connection with the pulley 14, supported by theshaft 4, by a band 15, the band being crossed to impart motion to thevarious parts in the proper direction.

From the plate 1, extend two shafts 16 and 17, the free ends of each andthe shaft 8,supporting grooved edged rollers 18, and to the face of theplate is secured a toothed rack 19, by a set screw 20, passing through aslot 21, in the plate, a stud 22, extending from the rack moves in aslot 23, giving direction to the adjustment of the rack, as shown atFigs. 3 and 5. Upon the shaft 16, is supported a sleeve to which issecured at one end a sprocket wheel 24, and to the other end an arm 25,from which projects a stud 26, and

upon the shaft 4, outside of the plate 1, is secured a sprocket wheel27, having a chain belt 28, connecting it with the sprocket wheel 24. Tothe face of the sprocket wheel 27, is secured an arm 29, supporting atoothed wheel 30, at its free end which meshes with a like toothed wheel31, secured to the end of the shaft 4, and to its face is secured a randcutter 32.

The face plate 33 is placed over the plate 1, of the main supportingframe and is provided with three irregular shaped openings 34, thecenter portion 35, held in position by the bridges 36. The center of oneof these centers being cut out as shown at 37. The grooved edged rollers18, are located in these openings so that the flanges of the rollerswill engage each face of the plate, the center portion of the rollersfitting within the openings. The roller located on the main drivingshaft 8, has a toothed wheel 38, secured to its rear face the teeth ofwhich mesh with series of teeth or pins 39, extending from the innerface of the plate 33, corresponding in outline with the irregular shapedopenings 34.

The plate 33, is provided with an opening 40, corresponding in shape tothe lift of the heel, and to the outer face of this plate around theopening is secured a trough or guide 41. To the inside of this plate issecured a roller 42 being located over the opening 40, the bearings 43supporting the roller being slotted in order that the roller may bevertically adjustable. A shaft 44, is also located in bearings securedto the inside face of plate 33, and curved rollers 45, are adjustablysecured to this shaft, their curvature corresponding in shape to thecurved portion of the heel of the shoe. To one end of this shaft issecured a toothed wheel 46.

The operation of my device is as follows: The leather 47, composing theheel is cut to the desired shape and size of the greatest lift of theheel, and a number of such lifts are glued together as shown at Fig. 6,and when desired is placed in the trough and projecting beyond the innerface of the plate 33, until even with the face of the toothed wheel 30,when the parts will appear in the position shown in the drawings.
